IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 190,723, dated May 15,1877; application filed March 27, 1877.

the same to be described in the following specification, and representedin the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 afront elevation, and Fig. 3 a transverse section, of my improvedwashing-machine, with its cover removed frOnI the tub. Fig. 4is alongitudinal section of the dasher and its supportingarms and springs.Fig. 5 is an inner side View of one of the said arms.

My invention relates to Or consists in, first, the combination of a tuband its Wash-board or corrugated lining, a notched dasher and itssupporting-arms, springs, and stops, all arranged and appliedsubstantially in manner and to Operate as specified; second, thecombination of the tub and its wash-board or corrugated lining, and itsdasher, and the supporting-wires, springs, and stops thereof, withmechanism, as hereinafter explained, for producing reciprocatingmovements of the dasher and its arms.

In this machine the tub or clothes and suds reservoir A has within it afiutcd Wash-board Or corrugated lining, B, arranged and formed as shown,it being to operate with a reciprocative dasher, U,.which is aboardrdisposed edgewise toward the lining B, and inclined thereto, inmanner as represented. This dasher at its ends enters straight groovesor sockets b b of two bent arms, D l), provided with journals E E, thatextend through boxes or bearings c o, xed on the upper surfaces Of theends Of the tub A. Each of the sockets b b is open at its lower end andclosed at its upper end, the closure d serving as a bearing for theupper end of a helical spring, e, arranged in the socket and in a notch,f, made in the dasher.

The said dasher is supported by the springs and the sockets, aud canmove forward and backward within the latter, or, in other words, eitheraway from or toward the corrugated lining. Two short arms or stops, g g,projectingfrom thedasher in manner as shown, serve, when against theclosures d d, to maintain the dasher in place Within its carrying-arms,which are connected by a rod, h, extending from one to the other, ashort distance above the dasher.

Each journal of the dasher has a crank, t', projecting from it, which,by means of one of two rods, k k, is connected with one of two y-wheels,l l, by a crank-pin, m, projecting from the wheel.

These fly-wheels, arranged as represented, are fixed to a shaft, m,extending along uuderneath and pivoted to the tub, and provided with abell-crank, n, connected to a pedal, o, by a pitman or link, p, allbeing arranged as shown.

By actuating the pedal, the dasher may be put in rapid reciprocatingmovement within the tub. By it and the corrugated lining, clothes may beWashed when the tub is supplied with water or a saponaceous solution.

Owing to the springs the dasherwill not be clogged by the clothes, as itwill give back in case of their becoming wedged or caught between it andthe lining.

With the machine as described clothes may be washed to advantage withgreat expedition, and little if any danger of being torn or injuredwhile being so cleansed.

I claim- 1. In combination with the tub A and its Wash-board Orcorrugated lining B, the notched dasher C and its recessedsupporting-arms D D, springs e e, and stops g g, arranged and appliedessentially as set forth.

2. In combination with the tub A and its wash-board or corrugated liningB, and with the dasher C and its recessed supportingarms D D, springs oe, and stops g g, arranged as set forth, the cranksi, connecting-rods kk y-wheels l l, cranked shaft m, and the pedal o, arranged as speciled.
